I created an FLA file that has a control bar (with play, pause, etc.) that I want to appear only when the mouse is moved onto the stage. When the mouse is moved off the stage, I want it to fade.

I used the code below but it seems that the MOUSE_OVER event is only captured when the mouse is moved over some object on the stage. When the mouse is over an unused part of the stage, the event is not fired and the control bar remains invisible.

Any help would be appreciated.

I'm working in Adobe CS3/AS3. I'm an experienced programmer but new to AS3.

barBg_mc is the name of the control bar in the code below.

Code:
import caurina.transitions.*;

stage.addEventListener(MouseEvent.MOUSE_OVER, event_ControlBar_Show);
stage.addEventListener(MouseEvent.MOUSE_OUT, event_ControlBar_Hide);

function event_ControlBar_Show(e:MouseEvent) {
	Tweener.addTween(barBg_mc, {alpha:1, time:1});
}

function event_ControlBar_Hide(e:MouseEvent) {
	Tweener.addTween(barBg_mc, {alpha:0, time:1});
}
